Enhancing Workforce Skills in Industry 4.0 through an E-Book on KUKA Robot Control and Maintenance

This study aimed to develop, evaluate, and determine the efficiency and effectiveness of an e-book on KUKA industrial robot control and maintenance. The e-book was designed to support both theoretical understanding and hands-on competencies, addressing the growing need for skilled personnel in the context of Industry 4.0. Its structure comprised five instructional units, instructional videos, end-of-unit tests, and reference materials. The quality of the e-book was assessed by five experts in content and instructional media, who rated it at a high level of quality (content: x? = 4.34, SD = 0.51; media: x? = 4.33, SD = 0.57). Efficiency analysis yielded E1/E2 = 85.13/81.13, exceeding the 80/80 standard. Effectiveness testing showed that post-test scores (x? = 186.60, SD = 8.09) were significantly higher than their pre-test scores (x? = 126.07, SD = 13.07), with results significant at the .001 level. These findings confirm the e-book’s effectiveness in enhancing learning achievement. The study highlights the value of digital learning platforms in robotics education and workforce development. The e-book offers a flexible resource that extends learning beyond face-to-face training and effectively strengthens technical competencies for industrial robotics.
